-------------------------------

Thanks [~gandras] for this work.

It will be very helpful to clusters with many queues. :D

>                 URL: https://issues.apache.org/jira/browse/YARN-10795
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: capacity scheduler
>            Reporter: Andras Gyori
>            Priority: Major
>
> Mostly due to CapacitySchedulerConfiguration#getPropsWithPrefix or similar 
> methods, the CapacityScheduler#reinit method has some quadratic complexity 
> part with respect to queue numbers. Over 1000+ queues, it is a matter of 
> minutes, which is too high to be a viable option when it is used in mutation 
> api.
